在这个编辑文件中，我必须选择相同的图片文件或另一个图片文件才能更新行。但我希望能够在不触及其他行的情况下更改我想要的任何内容。有什么想法吗？

<?php

include ("../header.php");
include ("../header2.php");

?>
<?php
include('../config.php');
include ('../ac.thumbs.php');

 if ($_GET['sil']) {
    $sil = htmlspecialchars(stripslashes($_GET['sil']));

    mysql_query("DELETE FROM CloseOut WHERE itemNO = $sil limit 1");
    echo "<h1>$sil item nolu kayit silinmistir</h1><br>";
}

    $edit = htmlspecialchars(stripslashes($_GET['edit']));
    //Resimlerin yuklenecegin yer
 $target = "../../upload/";

看看这段代码：

if(move_uploaded_file($_FILES['resim1']['tmp_name'], $target1)) 
{   
    mysql_query("UPDATE CloseOut SET $updates WHERE itemNO='$edit' ");
    echo "Tebrikler, ". basename( $_FILES['resim1']['name']). " isimli dosya yuklendi ve database'e basariyla islendi!<br>"; 
}

如果您不上传任何内容，那么move_uploaded_file将返回 false 并且您的更新将永远不会发生。
